Question about ITA vw

[VWralley]

just to clarify,

ITB 8v (it is a digi car) an i can run MS. but i have to retain an use the stock AFM?

ITA 1.8 or 2L 16v, but must retain correct CIS

[shwah]

The if it doesn't say you can, you can't rule is hard and fast in IT.

You have the option of CIS-E and a 1780cc motor, or CIS-E Motronic and the 2 liter for an ITA VW. FWIW, I don't beleive there is an outright power advantage to the electronic fuel injection over the CIS-E, but I will be building one over the winter to find out for sure.

Yes in ITB, you can run all of the digi hardware and control it with any ecu you like - but you still have to pull all the air through the AFM, you don't have to use that signal for anything, but the air has to pass through a stock AFM.

For ITA I would go small bumper 1.8 CIS-E. The 1.8 head will flow a bit better on the top end than the 2.0 head. The weight advantage is worth more than the 2.0 in a season worth of racing consumables. Heck, I have thought at times of putting a 16v in my car and seeing how it runs in ITA - but I have a lot of fun with ITB right now.

Where are you located? Few ITB cars sounds like west coast...

ok i just was looking for a hard "no" or "yes" thank you!

I'm in washington, an i dont really have the funds to travel to where i could run with a large ITB group. Im still definatly entertaining the idea of the 16v, i just love my megasquirted 16v rabbit, so much more than cis! haha

i was definatly leaning towards the 1.8 small bumper route..

while it would be nice to just ditch CIS-E, you cannot. But you are still allowed to tune CIS-E and if your brave and have a few spares go ahead and mess with the DPR calibration (I dont mean the idle calibration either, this is the screw on the back fo the DPR) before you go the route of a resistor inline with the coolant temp sensor.

[VWralley]

im really really not into messing with cis-e at all haha

sorry fellas but i may have to move into the production category. although i may start out in ITB to learn the ropes a bit

Chris, I believe the GCR says ...working AFM....but I guess if the vane moves it is working Chuck

[lateapex911]

Chucks right, it must be there, and function as stock, but, the ECU doesn't HAVE to listen to it's signal. With the MAP sensor allowance, there are options.....

[VWralley]

ah ok i see what you guys are saying. mine as well just build it to ITB spec an then if i choose to update motors i can run with those rules...

now back to the engine/car setup...if i run the 8v digi motor, will i also be required to stick with the big bumpers?
